Overview

AI-generated overview

Hosted MCP service that compares two CSV exports by shared key columns and reports changed, one-sided and ambiguous rows for a small USDC fee.

What you can do
  • Compare two CSV tables by one to four shared key columns and get a report of changed values and rows present on only one side.
  • Flag ambiguous rows caused by duplicate or missing keys, with case-sensitive exact string matching.
  • Run free tools (ping, service info, demo) on synthetic input to see the deterministic engine before paying.
  • Call the same logic over REST by appending a run path to the service URL.
When to use it
Useful when you need to diff two exports of the same dataset, such as before-and-after snapshots or two supplier or system extracts, and want a structured list of what changed. Worth adding if you already have x402 payment support in your MCP client and the files fit the stated size limits.
Requirements
A Streamable HTTP MCP client pointed at the hosted endpoint; no account is required. Paid tools need a client that supports x402 payment on Base (eip155:8453) in USDC. Inputs must stay within limits: 1 MiB UTF-8, 5,000 data rows, 64 columns per file.
Before you install
Each successful report costs 0.05 USDC on Base; verify the network, asset, amount and recipient in the payment requirement before authorizing, and note a manual transfer alone does not unlock a report. Submitted CSV data is processed in memory but passes through Cloudflare and the hosting provider, so only send data you are authorized to share. The service is newly launched and a real paid settlement was not tested at launch.

Installation

In SourceWeft

  1. Open UNLAV CSV Reconcile in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Ivansky1%2Fcsv-reconcile/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

UNLAV Data Tools MCP

Connection metadata for two hosted MCP services. Both use Streamable HTTP, offer free fixed examples, and charge 0.05 USDC on Base per successful report through x402 v2. No account is required.

Setup and examples ? Machine-readable directory

Try it without paying

Connect either endpoint using a Streamable HTTP MCP client. Call ping, service_info, or demo with {}. The demo uses synthetic input, runs the actual deterministic engine, and is free. Free tools work in ordinary MCP clients; paid tools require x402 payment support.

Use the complete example returned by service_info as the paid tool arguments. A valid unpaid call returns an x402 payment requirement. Verify the requested network, asset, amount and recipient before authorizing payment. A manual transfer alone does not unlock a report.

REST is also available: append /run to either MCP URL and POST the same JSON input. Append /openapi.json for the input schema or /demo for the free example.

What each service does

CSV Reconcile compares two CSV exports by one to four shared key columns. It reports changed values, rows found only on one side, and ambiguous duplicate or missing keys. Values are case-sensitive exact strings. It never edits either file. Limits per file: 1 MiB UTF-8, 5,000 data rows, 64 columns, 131,072 characters per cell, 20,000 parsed records including blanks. Detail lists stop at 2,000 discrepancies; counts cover all accepted rows.

Supplier Quote Compare ranks suppliers for the same complete order. It uses exact integer arithmetic for two-decimal prices and adds the stated shipping once. Missing required SKUs exclude a quote from ranking; equal totals share rank. Limits: 20 suppliers, 200 required SKUs, one currency. It does not infer taxes or FX, verify availability, recommend suppliers, or place orders.

Payment and privacy

Price: 0.05 USDC on Base (eip155:8453), per successful report. The x402 service returns the exact canonical USDC asset and recipient in its payment requirements. Settlement is handled through PayAI; this metadata repository contains no wallet or signing secrets.

Inputs and reports are processed in memory and not saved in application receipt logs. Requests traverse Cloudflare and the hosting service. Submit only data you are authorized to share. The service records payment transaction references separately; deployment tests and synthetic examples are not customers or revenue.

These are newly launched services. Public MCP/REST discovery, synthetic outputs and unpaid payment challenges have been verified. A real paid settlement was not performed during launch testing.

Support: [email protected]. Include the service, request timestamp and transaction hash. Do not email customer files, account credentials or wallet secrets.
